yor preferably force feeding means, and thereby the liquid fuel become vaporized in transit to the jet orifices so that from the orifices a jet of high velocity vapor is discharged and mixed with air so that a large hot, white iame is produced. A

The invention has for its general object to improve the general construction and operation of devices of this character so as to be reliable and efficient in use, to providev a burner which will be comparatively simple and inexpensive to manufacture and so designed as to enable the burner orifices to be easily and quickly cleaned, and particularly to provide a burner whereby the greatest amount of heat possible isobtained from a given amount of fuel. Y

With these and other objects in view the invention resides and consists in the con struction and novel combination and arrange- Y ments of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope ofthe claim may be resorted to without departure from the spirit or sacrificing any of the advantages of the invention.

Similar characters of reference denote like or .corresponding parts throughout the several figures of the accompanying drawing forming a part of this specification, and upon which,

Fig. 1 shows a sectional plan view of a steam boiler to which my improved burner is shown applied, and p Fig. 2'is a side view of the burner shown in Fig. 1.

Referring in detail to the characters of reference marked upon the drawings, 5 rep resents the base of a heater, 6 the water chamm ber, 7 a combustion chamber in which the burner, again to be referred to, is positioned.

8 indicates an opening into the combustion chamber, and 9 a door for normally closing the same. 10 indicates a return pipe from which formsa trap 25 and through which the y radiators,`not shown, and connected to the l lower portion of the boiler.

The burner, as before suggested, is preferably provided with forced draft means in the form of a motor, indicated as 11, and ap pump 12 connected with and operated by the `motor, said pump being positioned intermediate of the fuel supply pipe 13. vThis pipe obviously is connected with a fuel tank,y

preferablyvlocated at an elevation with respect to the burner. In some installations it is possible to place the fuel tank high above the burner and therefrom sufficient pressure may be obtained to insure a proper feeding of the oil without the necessity of the pump, but since it is vnot always practical to place ythe tank in this preferred raised position an electrically operated pump may be provided in the service pipe to insure the forced feed if it is desired. l Within the pipe line 13 I provide a shut-off valve 14 whereby the liquid fuel supply from the tank, not shown, is controlled. 15 indicates a check valve which is positioned in the pipe line adjacent to the shut-off, 14, before mentioned for the obvious purpose of permitting the liquid fuel to be fed to the burner and to prevent the fuel and gas to re-act infany way upon the fuel supply. A regulation valve 16 is next provided in the pipe line, this may be of any preferred design, such as the needle valve 16 represented in the drawing, and is provided with level` connections 17 so as to be operatable from a thermostat or other heat regulating means,

not shown.

From this valve the liquid fuel supply 1s `led to the burner through a substantially horizontal pipe 18, passing through the opening 19 and door 20. vThis pipe may be con nected with the upper part of and form an integral part of the coil 2l, that is positioned ab'oveand surrounding the burner plateQQ. The lowermost part of this coil extends out beyond the other parts of the coil and is carried upward where it is connected with a horizontally arranged enlarged tubular member 23 .that is disposed partly across the top of the coil and over the .burner and the fiame arising therefrom, thereby` forming a retort 23 in which the heatedv liquid fuel is finallyv transformed into a gas or vapor preparatory to its passage to the burner proper. The opposite end of this retort is connected by vertically and horizontally disposed piping 24 gas is passed en route to the burner plate 22. be purpose of the trap is to prevent the overflowing oi oil in case the tire should be put out and the shut-oit valve 14 not closed. This plate is hollow and connected by an inlet pipe 2G upon one side and a blowout pipe 27 on the other, and is further provided with a series of a suitable number of holes in its top side to constitute the jet orifices where the escaping gas is consumed. rlhe blowout pipe 2'? is provided with a valve 28 which is normally lrept closed, but which may be opened from time to time as the case may require in order to blow out any sediment which may accumulate in the burner. The burner is adapted to be placed in almost any kind of the commercial designs of furnaces such as are used for house heating, and is preferably placed above the grates and supported by ire bricks 29 or other suitable means, as is suggested by the illustration shown in Fig. 2.

l Having thus described my invention what l claim is new and desire to secure by Letters Y Patent is A burner comprising a coil, a liquid fuel supply pipe connected with its upper portion, Valves in said pipe line to control the supply ot liquid fuel, means for providing aforced feed of the fuel through the feed pipe, a relatively large heat retort disposed across the top ot' the coil in therpath ot the flame from the jet orilices of a burner, the inlet end portion of said retort being connected with the lowermost part of the coil, a trap connected with the discharge end portion of said retort, a burner positioned below and central of the coil, a pipe connecting said trap and burner to supply fuel thereto, and a blow-out pipe directly connected with the burner. y
